The on-site management at my UDR-owned complex was fine, but anything that went to corporate (anything having to do with rent or move-out fees) is a disaster. Their "customer service" staff are abusive, hostile, and care about nothing but getting every possible dollar out of you. Trying to escalate and talk to someone at corporate about their customer service reps was a waste of time; they never return messages sent through the website or even calls made directly to their voicemail (the on-site management was happy to give out direct phone numbers for corporate). They will also lie about the status of your apartment at move-out. I'm paying above and beyond my security deposit about things that are not true but that I can't afford to lawyer up about. Also they're breaking the law in my county for their pet fee policies, which I've reported to the county. UDR is the worst, don't rent from them.
